Automaker EV charging coalition IONNA has more than doubled its U.S. network in 2026 hero imageIONNA, the EV charging network founded by eight automakers, announced Wednesday that it has surpassed 180 live charging sites across the U.S., more than doubling its footprint since the start of 2026. The company also earned the top ranking among DC fast chargers in J.D. Power's 2026 U.S. Electric Vehicle Experience Public Charging Study in the first year it was eligible for the ranking.IONNA's eight founding members are BMW, General Motors, Honda, Hyundai, Kia, Mercedes-Benz, Stellantis, and Toyota. The network says it is the largest 400 kW charging network in the U.S."The industry has treated charging scale and charging quality as a tradeoff. Our growth and first-place customer satisfaction ranking show that drivers can and should expect both," IONNA CEO Seth Cutler said in a statement. "The IONNA team is focused on delivering quality at scale to enable the sale and adoption of EVs in North America."The company started 2026 with 80 sites, according to InsideEVs. Cutler told InsideEVs the company hit its 100th site on its second-year anniversary before accelerating further through the year. Despite the expansion, IONNA is not the fastest-growing charging network in the U.S. — Tesla installed more chargers in the second quarter, with Walmart in second place, according to InsideEVs.Since IONNA announced its Circle K partnership in April, the company said more than 40 charging locations at the convenience store chain have opened their doors to drivers. According to Electrek, the Circle K locations are equipped with 400 kW chargers supporting both NACS and CCS connectors, and IONNA aims to eventually bring its charging to more than 350 Circle K locations.Drivers of vehicles from four of IONNA's founding automakers — BMW, GM, Hyundai, and Mercedes-Benz — are now eligible for 10% charging discounts through their automaker apps and Plug & Charge, the company said. IONNA said the remaining founding automakers will follow. Volvo drivers now have Plug & Charge support on the network, with Toyota and Lexus support expected in October.IONNA has also added integrations with Presto, ChargeHub, and EV Connect, expanding its roster of supported partner platforms to 19 in total. The company has opted against launching its own app, making its chargers accessible instead through an array of third-party platforms.The company also announced the formation of a Driver Advisory Council to gather feedback on network performance and future product development. The council is co-captained by Kyle Conner of Out of Spec and Tom Moloughney of State of Charge, the company said.IONNA plans to deploy 30,000 plugs across the U.S. and Canada by 2030, according to InsideEVs.
